I use the Printf package for that.
v := 65.456.
'With 2 decimal digits: %5.2f, or 3 like this: %6.3f'
printf: {v. v}.
With 2 decimal digits: 65.45, or 3 like this: 65.456
It is in http://www.smalltalkhub.com/#!/~philippeback/HOExtras
Printf
I am just used to C printf and well, I like the way it works.
